DIRECTION-INDICATOR FOR AUTOVEHICLEF' Specification of Letters Yatent.

Application filed April 9, 1918. Serial No. 227,585.

.novel featuresherein shown, described and claimed.

Figure l is a. perspective of the front end of an automobile provided wlth direction in diastole-embodying the principles of my in-- vention.

Fig. 2 is e. view analogousto Fig. 1, and showing amodified construction.

Fig. 3 is 'a. fragmentary detail of one of the joints and showing the circuit breaker. Fig. 4 is a horizontal section on the line 44 of Figs. 1,3 and 5.

Fig. 5 is a diagreuunatic view of the compressed air system shown in Fig. 1. P

Fig. 6 is an enlarged detail elevation of on indicating arm and flagstafi' holder.

Fig. 7 is a horizontal section on the line 7'7 of Fig. 6. The posts 1 and 2 are rigidly mounted at points outwardly and forwardly of the ,front corners of the radiator 3, the lower ends of the posts being clamped to the frame and the upper ends of the posts being bracketed to the radiator. is a flat bearing plate 4:. A boss 5 extends backwardly from the plate 4 and is slidingl' mounted upon the post 2 and held in ad justed position by set screw 5.

The plate 4 is in line crosswise of the line of travel and has a bearing face 6 on its front side. The electric cable 7 passes upwardly through the hollow in the post 2; said post being a pipeand the cable passing from the upper end of the post through an opening in the plate 4. to a. soring contact 8 secured upon the front face of the plate 4.

"1 A bearing plate 9 has an annular flange 1O fitting the annular bearing seat 6 of the plate 4 and a stud 11 is screwed into the late .4 at its axial center and extends hrough the center of the bearing plate 9, imd a nut 12 is placed upon the stud to hold he plates'together. -A helical spring 13 is placed upon the stud 11 between the plates 4 and 9, one end of the spring engaging a boss At the upper end of the post 2 mg the boss 15 upon the plate 9.

A crank arm 16 extends from the plate 9 14 upon the plate 4: and the other e .d engaglPatented Meir. it, i iiii. v

inwardly and downwardly and has been ing i 17 in its inner end.

I he socket 18 extends upwardly from the plate 9, the pipe indicator arm 19 is screwed into the socket 18, a reducer i9 is screwed upon the upper end of. the pipe 19, and e nipple 19 is-screwed into the reducer. The

lamp 20 has a socket 19 screwed upon the nipple 19. A fiagsteff 21 carrying the ting 22- is mounted between the jaws of the clamp 23. The clamp 23 is e strap bent upon itself to form the bearing 23 loosely encircling the nipple 19 and forming the jaws 23" and olt and Wing nut 23 is inserted through the arms of the clamp between the nipple i9 and the fiagstaii 21. so that by manipulating the Wing nut, the flagstaii' may be raised or lowered and rigidly clamped in adjusted o sition and at the same time the fiegsta-fi is free to revolve around the nipple 19 The tension of the spring 13 is exerted to hold the indicator arm 19, the lamp 20 and thefiag 22 upright. A piston cylinder'Qe is;

r mounted beside the postfi. a piston 25 slides in the oyhnder 24, and the piston rod 26 is v connected to the bearing 1'? by a link 2?.

The air tank 28 is mounted under the seat.

he control valve 29 is mounted upon the instrument board. The pipe 30 leads from the air tank to the control valve 29 and the pipe 31 leads from the control valve 29 to the cylinder 24, so that when the control valve 29 is operated one way, the oil passage is opened from. the tank 28 tothe cylinder 2i and the pressure of the air will raise the pie ton 25, overcome the tension of the spring 13 and throw the arm 19, the lamp 20; and the flag 22 outwardly to a horizontal position, as shown in dotted lines in Figs. 1 and 5. This will indicate that the driver of the machine intends to turn to. his left, and when the control valve 29 is operated the other Way, the air pressure from the cylinder will be exhausted to allow the spring 13 to return the indicator to vertical and normal positions. In a like manner the indicating arm 32, the lamp and the flag 34 are mounted upon the post 1 and operated by the cylinder piped to the tank 28 through the control valve 36.

The wires 37 oxteml downwardly from its t the indica the lamp 20 through the post 19, said post being of pipe, and the lower ends of the wires extend across the inner face of the plate 9 and are attached to' the spring contact 38, so that when the arm 19 swings to horizontal position the contact 38 will en gage the contact 8 and light the lamp.

The lamp 33 is operated in a similar manner. 1

In the modified construction shown'in Fi 2 a rock shaft 39 is mounted'under the si e bar 40, a crank arm 41 connects the forward arm ofthe rock shaft to the link 42 and the upper end of the link 42 is connected to the bearing 17 upon-the arm 16. A crank arm 43 is connected to the rear end of the rock shaft 39 and extends in the opposite direction from thecrank arm 41, and a pedal 44 is connected to the outer end or the crank arm 43, the stem .45of the'pedalezitending through the bottom board in front of the q I curing the lower end of the post-,aliracket operator, so that by pressing downwardly on the pedal 44 the indicatingarm 19, the lamp 520 and the flag 22' will be swung outwardly,

the same as by operating thec'ompressed air system in-Fig. 1.

In a like manner thepedal 46 controls ting arm- 32; the lamp 33 and" the fla 34; The studs 1 1 are plvo'ts rigidly mounted. The plates 9 arejbearings mounted uponthe pivots. The armsjlfi and bearings 17' constitute operating, arms. The indicatorarms 19 and 32 are -xed t the'pivotedbearings at right anglesto the operating arms and 'the lamps 20 and 33 and the flags22 and 34 are indicators mounted upon the. indicating.

arms.

In Fig. 1,1 have shown compressed air' means for moving the operating arms upwardly to swing theindic'ating arms and indicators outwardly.

The springs 13 constitute means for holding the indicating armsand indicators up right, and in Fig. '21 haveshown mechanical means for moving the operating arms upwardly to swing the indicating arms and ariou's changes may be made in the constructiqn, combination and arrangement of parts without departing from the spirit of my invention as claimed.

I claim:.

In a directionindicator, a post adapted to be mounted outwardly and forwardly otthe front corner of a radiator, a clamp for sethe post, a second bearingwplatepivotally connected tothegfirst bearing-plate, a crank armextending= ronr the second bearing plate inwardly and downwardly, asocket extending upwardly jfrom the second bearing plate, an indicator armfixedj in the socket,

an indicator securedtothe indicator arm,

and means-for operating thewcrank arm to v swing'the indicator arm from a vertical position'outwardly and backwardly',

In testimony-whereof I have signed my name to this specification.

CHARLES. W; roasts.
